Britain have picked up their second gold medal of the World Championships after victory in the women's quadruple sculls in Japan on Sunday.
Katherine Grainger, Frances Houghton, Rebecca Romero and Sarah Winckless edged out Germany by just 0.34 seconds.
And there was a bronze medal for the women's lightweight quadruple sculls of Tanya Brady, Lorna Norris, Hester Goodsell and Naomi Hoogesteger
The medals come just 24 hours after Britain's men won the coxless fours.
Britain's victory in the quadruple sculls was one of the closest finishes of the championships so far.
"We played every one of our strength cards in the final"
The turning point of the race came with 750m from home when the German boat was briefly caught up by a buoy to lose time to the Brits.
The win was a sweet moment for Grainger, who considered quitting last year after failing to win gold at the Athens Olympics.
"This has been tough because we were the crew that others looked out for after all our success this season," she said.
"But the biggest pressure we've faced is what we put ourselves under - we had high expectations and now we've achieved them.
"We played every one of our strength cards in the final - it's just massively satisfying that we got it right."
The women's lightweight quadruple sculls, taking part in only their third race, were involved in a tense battle with the Danish boat but faded in the closing stages and had to settle for third.
Canada claimed gold in a time of six minutes, 19.87 seconds.
"We concentrated on coming out quickly, which is something we only managed in the repechage," said Norris.
"At one point I just called 'Go' and there was a surge, so the guys know what to do. Lightweight women's sculling is going back on the map."
The team now have a total of four medals from the championships - their initial goal coming to Japan.
But it could have been even better only for the men's eight to miss out on a bronze medal in their final by two seconds.

They finished fourth behind winners the United States, Italy and Germany.
However, the women's eight of Beth Rodford, Natasha Page, Anna Bebington, Carla Ashford, Natasha Howard, Jessica Edge, Katie Greaves, Alison Knowles and Caroline O'Connor finished fifth in their final.
There was success for Ireland on Sunday when their men's lightweight four won a silver medal.
They finished nearly one-and-a-half seconds behind eventual winners France.
